Abstract

This paper deals with the applicability of electrical resistivity tomography (ERT) for the recognition of large landslide structures at depths, which have never previously been imaged accurately. One of the most studied and instrumented deep landslides in Europe is taken as an example: the La Clapière landslide. The first stage of the study consisted of an accurate geological mapping taking into account a morphological analysis of gravitational deformations. This allowed a very fine definition of the landslide structure, that could be compared with 3 provided ERT profiles performed within the landslide body. Very good correlations were obtained for the determination of sub-horizontal structures and associated fluid circulations. It confirmed the position of the sliding surface that reached a maximum depth of 100 m
